FRANZ X. \VAGNER, OF NEW YORK, N. Y., ASSIGNOR TO THE WAGNER TYPEVVRITERCOMPANY, OF SAME PLACE.

PAPER-CARRIAGE AND INDEX MECHANISM FOR TYPE-WRITERS.

SPECIFICATION forming part Of Letters Patent NO. 624,135, dated May 2,1899.

Application filed December 12 1898. Serial No. 698,967. (No model.)

To all whom it may concern.-

Be it known that I, FRANZ X. WAGNER, residing in the city, county, andState of New York, have invented certain new and useful Improvements inPaper-Carriages and Index Mechanisms for Type-Vriters, of which thefollowing is a specification.

My invention relates to paper-feed mechanism and to index mechanism fortypewriters; and said invention consists in the novel arrangement andcombination of parts hereinafter described and claimed.

Type-writers have heretofore been devised which employedseparatelymounted marginal feed-rollers that were adapted to bear uponthe paper near each side edge of the paper and a central feed-roll nearthe front of the platen and main feed-rollers that were adapted to bearupon the paper throughout a considerable extent of the length of theplaten. In such constructions, however, these feed-rollers or sets offeed-rollers have been separately moved and maintained out of actionwhen it was desired to straighten the paper on the platen. It will beunderstood that the several movements required to move thesefeed-rollers out of and into contact with the platen occasionedconsiderable delay every time it was found desirable to adjust the paperon the platen.

The object of my invention is to overcome the difficulties heretoforeencountered in type-writing machines and to provide a'simple andefficient mechanism for simultaneously throwing the feed-rolls whichcooperate with the paper-platen out of operation by a single operationof a hand-actuated lever.

A further feature of my invention consists in moving an indicator to andfrom the printing-pointby a movement of the lever which causes thefeed-rollers to be moved into and out of contact with the paper-platen.

In the accompanying drawings, wherein like characters indicatecorresponding parts in all the views, Figure 1 is a plan view ofsufficient number of parts of a type-writing machine to illustrate myinvention. Fig. 2 is a front view of the same with parts removed for thepurpose of clearerillustration, the paper being shown in place in thepapercarriage. Fig. 3 is a bottom view of the platen-carriage and theparts carried thereby. Fig. 4 is a transverse sectional view of some ofthe parts illustrated in Fig. 1, the

View being taken on the line 4 4 of Fig. 1. N

Fig. 5 is a detail perspective view of the cen tral-feed-roll-displacingcam and its carrier.

I have illustrated my invention in the pres ent case as adapted to thewell-known Underwood type-writer. It will be understood, however, thatmy invention may be employed in any form of machine wherein anapplication of said invention is found feasible and that changes indetail may be made to adapt my improvements to other types of machinesthan that illustrated.

In the drawings, 1 indicates the main frame of an ordinary Underwoodmachine, in which a paper-carriage 2 is adapted to reciprocate from endto end for the production of lines of writing. The paper-carriage 2 isprovided wit-h an auxiliary frame 3, which constitutes the platen-frameor carriage proper. In this platen-frame 3 is carried the platen 4,which may be rotated in any suitable manner to produce the spacingbetween the lines. Suitable mechanism (not shown) is provided for movingthe platen-frame in a vertical direction in the carriage to bringtheprinting-line into alinement with either the upper or lower casecharacters a h, respectively, on the typeb'ars. (See Fig. 4.) Theplaten-frame or carriage 3 isprovided with a paper-shield 5,which guidesthe paper to the platen. This shield extends from the rear portion ofthe platen, as indicated in Fig. 4, to a point below the central frontportion of the platen, as indicated at 6, and apertures 7 are providedin the shield, through which apertures extend the main feed-rollers S.The feed-rollers 8 are shown as three in number and are loosely mountedupon a shaft 9, which is carried by arms 10. These arms 10 are providedwith sleeve-like portions 12, that carry ratchetfaces 13, which engagein corresponding ratchet teeth upon sleeves 14, which are looselycarried upon a rod 15, and the sleeves 14 are preferably provided withopenings 16. Each of the sleeves 14 is connected to a coiled spring 17,which is in turn connected to a sleeve 18, fixed to the shaft 15. Itwill thus be seen that a rotation of the sleeves 14 will increase ordecrease the tension of the springs upon the arms 10 and feed-rollers 8in accordance with the direction in which said sleeves 14 are turned. Itwill of course be understood that the engaging teeth between the sleeves12 and 14 will maintain the parts in the relative positions to whichthey are adjusted. The shaft 9, hereinbefore referred to, is extendedbeyond the arms 10, as indicated in Fig. 3, and these extensions areprovided with cams 19, which cooperate with arms 20 near each end of theplaten, that are adapted to slide in the longitudinal direction of theshaft 9, as will be hereinafter explained. These arms 20 are fixed upona longitudinally-movable rod 21, that slides in bearings 21 of theplaten-frame, and said arms are extended upon the opposite side of saidrod to form extensions 22. These arms or extensions 22 are each providedwith a cam-finger 23,'which cooperates with an abutment or extension 24,connected with the support 25 of each of the marginal rollers 26. (SeeFigs. Band 4.) These marginal rollers 26 are adapted to bear upon thepaper near each end of the platen and are, as before stated, carried bythe supports 25, which in the present instance consist of spring-armsbent, as indicated at 27, Fig. 4, and secured, as indicated at 28, to aportion of the platen-frame 3. It will thus be seen that the marginalrollers 26 are independently mounted near each end of the platen and areadapted normally to be maintained in contact with the platen by thespring-pressure of the supports 25, in which they are mounted, and thata movement of the rod 21 in one direction will cause the cam-fingers 23to move the marginal rollers 26 out of contact with the platen or thepaper on the platen, whereas a movement of said rod in the oppositedirection will bring the lowest portion of the cam-fingers 23 under theabutments 24, thereby allowing the rollers to simultaneously move intocontact with the platen or with the paper on the platen. In order tobring about this longitudinal movement of the rod 21, I have provided ahand operated lever 29, which is pivoted, as indicated at 30, upon theplaten-frame and is provided at its lower end with a slot 31, in which apin 32 upon the rod 21 engages.

Upon reference to Fig. 2 of the drawings it will be observed that anindependentlymounted feed-roller 33 is pivoted in a springpressed frame34, secured to an extension 35, (see Fig. 4,) extending from the rod 15.This spring-pressed feed-roller 33 is adapted to be forced through anaperture 36 in the shield 5 and to be normally maintained in contactwith the paper-platen by the pressure of the spring-pressed frame ofsaid feed-roller. This spring-pressed frame or support 34 is providedwith a pin 37, (see Fig. 4,) with which cooperates a cam 38, (shown indetail in Fig. 5,) carried by the longitudinally-movable rod 21. The cam38 is so located with relation to the pin on the spring-pressed support34 that the roller 33 will be moved out of contact with the platen whenthe longitudinally-movable rod 21 is moved in a direction which willcause the marginal rollers 26 and the main feed-rollers 8 to be forcedout of contact with the platen, and the parts will be maintained in suchposition untilthe rod 21 is moved in an opposite direction by thehand-operated lever 29. The rod 21 is likewise provided with studs 39,each of which carries a pin 40, that passes through a cam-groove 41 in am ovable indicator-bar or scale 42. This scale 42 is connected by a link43 to one end of the platen-frame, as indicated at 44. This scale ismounted so that the upper edge thereof may be brought directly beneaththe line of writing by the hand-operated lever 29, as indicated in Fig.2 of the drawings, whether the platen be in the lower or elevatedposition. This is due to the fact that the scale and its cooperatingparts are carried by and moved bodily with the platen-frame. The indices45 upon said scale are so arranged that no matter at what point thecarriage be with relation to the printing-point an index 45 will alwaysbe brought to the printing-point when the scale is elevated by thehand-operated lever 2.). The indices are equably arranged, so that anyone index brought to the printing-point will indicate the relativepositions of each character throughout the line, as the spacing on thescale corresponds to the distance between the characters written. Itwill thus be understood that the scale not only affords an indication ofthe printing-point, but that it likewise indicates the line on which thecharacters will be written. However, where an indication of the linealone is desired the bar 42 may be made without indices thereon. \Vhenthe scale is moved by the hand-operated lever 29 to the dotted-lineposition represented in Fig. 2 of the drawings, it is conveyed to aposition where it does not interfere with the writing, as will be seenby reference to Fig. 4 of the drawings. In this view a typebar 46 isshown in the printing position with a ribbon 47 interposed between thecharacters on the type-bar and the paper on the platen. This ribbon 47is carried by suitable mechanism-such, for instance, as a guide 48-whichin the present instance is automatically operated by suitable mechanism(not shown) to convey the ribbon into the path of the characters on thetype-bar j ust before such character reaches the platen and toautomatically move the ribbon out of the line of writing after eachcharacter is written.

It will be observed that by my invention I am enabled to move all of thefeed-rollers into and out of contact with the platen and tosimultaneously move the scale or indicator to the position where it isavailable to indicate the printing-point and the position of a line ofwriting and that the only movement required to bring about this movementof the scale and the feed-rolls is that given to the hand-operated lever20, whereas in the type of machine wherein such rollers were heretoforeemployed it was necessary to make several movements in order to carrythe marginal, central, and main feed1'ollers out of contact with thepaper on the platen.

The indicator or scale is seldom required except when the paper is to beadjusted upon the platen, and when this is necessary it is desirable toforce all of the feed-rollers out of contact with the paper on theplaten, so that the paper will be entirely free from the pressure of thefeed-rollers and may be readily moved to any position desired. Inaccordance with my invention the rollers are moved out of contact withthe paper, and the scale is automatically moved into the indicatingposition and is automatically moved out of such position when therollers are again allowed to bear upon the paper.
